Answer:
9
Step-by-step explanation:
we know by definition that

so now we evaluate

and if we want to do an extra step

which works.
Answer:
y + 7 =
(x + 6)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m =
and (a, b ) = (- 6, - 7 ) , then
y - (- 7) =
(x - (- 6) ) , that is
y + 7 =
(x + 6)
Answer:
C) 4
Step-by-step explanation:
Answer:
x = 13
Step-by-step explanation:
Here, we want to get the missing side
from what we have, the triangle is a right angled triangle
In this kind of triangle, the Pythagoras’ theorem works
The square of the side facing the right angle ( marked x here) is equal to the sum of the squares of the two other sides
We have this as;
x^2 = 5^2 + 12^2
x^2 = 25 + 144
x^2 = 169
x = √169
x = 13
